Abstract
A nozzle for spouting a liquid phase, in which one liquid phase in a two-liquid phase system can be stably jetted as highly dispersible droplets while suppressing coalescence of droplets, and accumulation of fine solid components in the nozzle hardly occurs. The nozzle has a structure in which capillary tubes or pores are assembled. Further, the capillary tubes or the pores are formed using a suitable material having a low affinity for organic or a low affinity for water, or a material subjected to appropriate surface treatment.

-20. (canceled)
A nozzle for spouting a liquid phase comprising:
- at least one structure for spouting a first liquid phase to a second liquid phase in a two-liquid phase system including an aqueous phase and an organic phase, in which a plurality of capillary tubes or pores that are open at both ends are assembled,
- wherein the two-liquid phases are brought into an emulsion state by spouting the first liquid phase sucked from a first end of said structure into the second liquid phase in the form of droplets from a second end of said structure.
A nozzle for spouting a liquid phase, the nozzle comprising:
- a plurality of capillary tubes or pores, each with an inner diameter of 0.5 mm or less, which spouts the liquid phase in a two-liquid phase system having an aqueous phase and an organic phase containing at least one of the particle components,
- both ends of a suction end for sucking the liquid phase and a nozzle discharge end for releasing the sucked liquid phase are open,
- the capillary tubes or the pores, in which the total length of the cylindrical or tunnel-shaped portion between the openings is at least twice the inner diameter, and the inner diameter is at least five times a maximum particle diameter of the particle component, are assembled, and
- an emulsion state is formed by spouting the aqueous phase or organic phase containing particle components as droplets from the nozzle discharge end into the other liquid phase, resulting in an emulsion generated.
A nozzle for spouting a liquid phase, wherein
- said nozzle is installed in an aqueous phase or an organic phase in a two-liquid phase system consisting of the aqueous phase and the organic phase,
- said nozzle has a structure including a plurality of small tubes or pores assembled at both ends of a suction end for sucking a liquid phase and a nozzle discharge end for releasing the sucked liquid phase are open, and an entire length of a tubular or tunnel-shaped portion having an inner diameter of 0.5 mm or less is at least twice as long as the inner diameter, and
- an emulsion state is formed by spouting the aqueous phase or the organic phase as droplets from the nozzle discharge end into the other liquid phase, resulting in an emulsion.
A nozzle for spouting a liquid phase as droplets, comprising:
- a plurality of capillary tubes or pores in which both ends of a suction end for sucking the liquid phase and a discharge end for releasing the sucked liquid phase are open, and an entire length of a cylindrical or tunnel-shaped portion having an inner diameter of 0.5 mm or less is at least twice as long as the inner diameter are assembled,
- wherein each of the plurality of the capillary tubes or the pores is assembled at a predetermined interval such that the droplets spouted from the nozzle do not coalesce.
